PIPE-CONNECTION FOR WASH-TUBS.

SPECIFICATION forming part of Letters Patent No. 425,553, dated April15, 1890.

Application filed May 4, 1888.

To all whom it may concern:

Be it known that I, BENJAMIN C. SMITH, a resident of the city ofBrooklyn, Kings county, New York, have invented Improvements inPipe-Connections for lVashTubs, of which the following is aspecification.

The object of my invention is to provide a series of expansible andcontractible pipes and connections for wash-tubs,w11ereby washtubs ofvarying dimensions may be readily connected to the soil-pipes.

The invention consists in the details of improvement and thecombinations of parts,that will be more fully hereinafter set forth.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which- Figure l is a vertical longitudinalsectional view of a series of wash-tubs provided with my improvedpipe-connections. Fig. 2 is an enlarged central sectional view throughthe pipes and connections, showing the details of construction; andFigs. 3 and 4 are modified forms of connections.

The letter A represents a series of stationary wash-tubs or wash-basins,of which there may be two or more, three being shown in the drawings.

a o, are the tubular outlet-plugs, that pass through the bottoms of thetubs or basins and are suitably held thereto. The tubular plugs a, arescrew-threaded externally beneath the tubs and receive nuts I), whichnuts each have an internal annular flange (Z at one end.

B are T or other shaped couplings, which at one part receive the smoothor unflanged ends of intermediate vertical pipes D, that are adapted toslide within the couplings B. The opposite end of each vertical pipe Dhas an external flange e. The flanged end of the vertical pipe D is heldin the nut h and the nut 11 drawn upon the plug a, the flange (Z on thenut pressing the flange 2 against the end of the plug a, thereby makinga tight connection. pipe D maynow be soldered to the coupling 13, ifdesired to make a close connection. Thus the plugs a are adj ustablyconnected with the couplings B by the intervening vertical pipes D,there being one coupling to each tub; but

The unflanged end of the vertical Serial No. 272,753. (No model.)

the intermediate vertical pipes D could be dispensed with and thecouplings be secured directly to the plugs a by the nuts I).

One or more of the horizontal branches of the coupling B have externalthreads to receive the nuts b that have inwardly-projecting flanges (ZAs in Fig. 1, every two couplings B are connected byahorizontal pipe Dof suitable lengtlnwhich is flanged at one end and unflanged at theother. The flanged end of each pipe D is held by the flange d of the nutb and drawn up close to the coupling by the nut. The other or unflangedend of the pipe D is now inserted in its proper coupling B for therequired distance and may be secured by solder, if desired. Thus it isseen that one coupling has the pipe D drawn close up by the nut b whilethe next coupling receives the unflanged end of the pipe.

Instead of securing the unflanged ends of the pipes D to the couplingsB, they maybe slipped loosely into the couplings and held in position,and leaking prevented at the junctions by the nuts b the flanges d ofwhich compress packing 0r washers f around the pipes D and between saidcoupling and the flanges (1 as in Fig. 3. p

There may be any number of plugs a and pipes and couplings connectedthereto. One of the couplings B connects by a pipe D with the soil-pipeor other outlet-pipe; but any of the couplings B could carry the pipe DAs shown in Figs. 1 and l, one of the pipes D is connected by the nut band flanges (Z and 6 directly with the plug a, while its unflanged endpasses freely into the coupling B.

As shown in Fig. 3, the coupling Bis a fourway coupling, and two pipes Dconnect said coupling with the end plugs a, while said coupling isconnected by the pipe D with the central plug a. The pipe D leads fromone branch of the four-way coupling; but the parts may be variouslyarranged and one or more intermediate pipes D not having flanges e, asin Fig. 4, could be inserted in the system where a greater length ofpiping is required. As shown, the packing will be held by the nuts 6 asbefore described, to prevent leakage.

With the above construction the plugs a may be. of varying distancesapart and be readily connected by the pipes D D and couplings B bypassing the unflanged end of a pipe farther in or out of a couplinguntil the required position is found. The parts are then I suitablyfastened. With this arrangementa system of piping for wash-tubs may besold that will fit any tubs, and an ordinary workman can readily set upthe piping. This is a great saving on the practice heretofore employedof measuring and cutting each pipe and then soldering the pipestogether. This system also overcomes the danger of becoming loosened andwater escaping.

Having now described my invention, What I claim is- The Wash-trays A,having plugs a in the BENJAMIN 0. SMITH.
